  • Patent number: 10869761
    Abstract: A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame. In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand. Tension in the tethers prevents the stent frame from rapidly expanding and optionally allowing recapture. Upon completion of the stent frame expansion, the tethers are withdrawn.

  • Patent number: 10867358
    Abstract: Processing payroll payments for employees is performed by a payment processing system and employee devices, so that the employee can with access security set short pay periods and have wage payments made according to their profile. The payment processing system has an interfacing server, a storage server, and a processing server, using internal signalling and file transfer. They receive from an employer computer net pay data for employees for a long period, and communicating with the employee devices to determine a desired payment split over the long period, and automatically notify an employee device of opening of a window for user editing of a payment split profile, and subsequently are instructed by the employee device as to edit the profile.

  • Publication number: 20200375770
    Abstract: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

  • Patent number: 10799352
    Abstract: Valve delivery catheter assemblies including components that limit trauma to the expanded prosthetic valve and body channels as the distal tip of the catheter is withdrawn through the expanded valve and thereafter from the body. Catheter assemblies according to the present invention can include a handle assembly, an introducer sheath, and a distal tip assembly. The handle assembly can include a fixed main handle and two or more rotating handles that allow a user to control the distal tip assembly of the catheter. A safety button can be included on the handle assembly to allow for precise and consistent positioning of the prosthetic valve in the body. A valve retaining mechanism can be included to assist in retaining the prosthetic valve prior to deployment.

  • Publication number: 20200246145
    Abstract: Methods of deploying and securing a heart valve prosthesis are disclosed. A heart valve prosthesis having a plurality of anchor guides is loaded within a catheter-based delivery device, wherein each of the anchor guides is releasably engaged by a respective elongate member and wherein tensioning of the elongate members aids in collapsing the prosthesis during loading. The delivery device is advanced via a transcatheter procedure to position the heart valve prosthesis at an implantation site. The heart valve prosthesis undergoes controlled deployment by controlling the release of tension on the elongate members. After deployment of the heart valve prosthesis, an anchor tool is advanced along at least one elongate guide member to the anchor guide associated therewith and positioned at a securement site. When the securement site is reached, an anchor clip is released from the anchor tool to secure the prosthesis to the heart.

  • Patent number: 10561497
    Abstract: A delivery system including a heart valve prosthesis and a delivery catheter. The delivery catheter includes an outer shaft component, an inner shaft component and a cinch mechanism. The outer shaft component has a capsule segment configured to encircle a first portion of the heart valve prosthesis and to thereby hold the first portion of the heart valve prosthesis in a reduced diameter state for delivery to a treatment site. The cinch mechanism surrounds a second portion of the heart valve prosthesis and is configured to hold the remainder of the heart valve prosthesis in a reduced diameter state for delivery to the treatment site. The capsule segment ends proximal of the cinch mechanism when the delivery catheter is in a delivery configuration. The capsule segment and the cinch mechanism in tandem hold the heart valve prosthesis in the reduced diameter state.
